This fizzy kids science experiment is a fun STEM activity for kids to promote fine motor skills, learn about color mixing, and engage the senses while fueling their curiosity!
Who does not love the chemical reaction of fizzing fun of baking soda and vinegar? And if you add some blasts of color, you have a timeless science meets craft – meets sensory play activity for all ages! Besides, you need just a few simple supplies, such as baking soda, vinegar, and food coloring, all of which you probably have at home already. This experiment is very captivating and an excellent way to teach little ones about chemical reactions. So, let’s get messy and have some science fun with this color-mixing fizzy science experiment!
Color-Mixing Fizzy Science Experiment
To conduct this fun, fizzy science experiment, squirt colored vinegar over the baking soda. Let a child use droppers to suck the vinegar and squeeze it onto the baking soda. This activity improves fine motor skills and strengthens the pincer grasp! Besides, when the two ingredients combine, they create a colorful chemical reaction– fizz!
This experiment is perfect for toddlers as it’s taste-safe with just two ingredients!
Below is the list of materials you will need to do this color-mixing fizzy science experiment:
*You can dilute the vinegar so it lasts longer and is less acidic.
First, start by pouring baking soda on a tray.
Then, mix a few drops of food coloring with vinegar in separate cups or bowls. Use as many colors as you’d like.
Next, squirt the tinted vinegar mixture over the baking soda and watch the magic happen! As baking soda (the base) reacts with the vinegar (acid), it causes baking soda to fizz and bubble.
As the mixture fizzes, it releases carbon dioxide gas, which will cause the colors to mix and blend in a beautiful and colorful display. This color-mixing bubbly reaction is sure to captivate your little ones!
Repeat the experiment as many times as you’d like, using different colors each time.

Benefits of using Tools:
Eye droppers are fantastic for strengthening small muscles of the hands and are great scientific tools for children.
Moreover, you can use squirt or squeeze bottles, which are another excellent hand-strengthening tool and are great for making a bigger fizz!
Also, offer a child to listen to the fizz, feel the texture, and describe the colors and bubbles. For example, ask them to observe what happens when they pour blue-tinted vinegar over yellow. [ It makes green.] All these prompts are great ways to develop observation skills. Don’t tell them; rather, ask them questions! What do you see? How does it feel?

Are you struggling with homeschooling? Below are 3 ways I can help you up-level your child’s early years!
Why Preschool Science?
Children are curious creatures. That’s why science experiments, even extremely simple ones, nurture their curiosity about the world. Learning to observe the experiment, express what they see, and predict what might happen are great tools for any little explorer! Besides, hands-on experiments promote essential practical life skills, boost motor control, refine hand-eye coordination, and so much more!
Why is this activity perfect for all ages?
This activity is perfect for toddlers since it is taste-safe with just two ingredients. Please be mindful that taste-safe does not mean edible! Also, you can dilute the vinegar so it lasts longer and is less acidic.
If you have a preschooler, add the waterproof alphabet, numbers, or shapes and turn it into a seek-and-find activity.
Moreover, older children can research the science of acid-base reactions and write a report.
And the best part is that cleanup is super easy! Once done, flush it down your drain, and the mixture will clean your pipes.
